my present improvement @ebrio-ent receptacl. n j eind the inner 'tube of receptacle is eziused to wedge at its lower extremity into the outer tube, whereby it becomes impossibler'or tbe lubricant to Work up between the tivo tubes. The lower eier-- 3&5 ti'emity of the outer tube or casing is dented to tit closely into 't'.i'e longitudinal groove oi tbe inner casing, vsind groove, by virtue of its engagement "with pin ut tbe top o outer casing', being' locked against rotary movement Within the outer ing during the rotation of the screw upon which tbe plunger of tlie'inner is nioiuitedA Hering brieiy outlined roi* improi'fed construe-tiem l uwill precetti t in detail. l'e

The body 01"' the lubricating device is eornposed of en outer tube 13 and an inner tube le, the outer tube being equipped With a number oi' pins/15 adapted to engage angular slots 16 formed in a cap 17 rovidedwith a. locking spring 18 perfor-atc i, as shown at 19, to receive one of the pins-whereby the cup, utter the' pins lieve been roperly adjusted to form the bayonet locli), is held s e- Icurely in place. 'The inner tube ltis provided'. vviti an exterior longitudinal groove 20, adapted to receive the inner protruding extremity 2l of one of the pins l5, when the part-s ere assembled; thus preventing the inner tul e from turning Within the outer tube for av purpose hereinafter explained. `Wl1en tbe tivo tubes 'i5-3 und le are assembled, the lower extremity ot' 'tbe enter 'tube is indent ed. eliown et 'whereby :i tight-joint formed between tbe nro tubes Where tbe 'groove 20 ie, located, tlius preventing the lubricant within the inner tube from entering tbe groove 2G et tbe bottoni und working up Werdly bett-e n tivo tubes. A inner extremity of tlieioutlr. tube is inwardly tiered zit-the bottmn. as shown et 23, and einee the said outer tube is composed of sheet metal, it will be slightly yielding et that point, wherebyi es the lower extremity. of

the inner tube approaches the bottom o the outer tube, during the assembling opera-tion, Ybe tufo tubes engage euch other, und, by the me tbe inner tube completely inserted,

en agement resulte in tightly Wedging members together ut tbe bottom tbe lubricant is prevented from eef ggg

working upwardly between the two tubes, the dent 22 formed in the outer tube, whereby the material of the latter is forced into the lower extremity of the groove 20 of the member 14, contributing to this result.

Vfithin the inner tube 14a' screw 24 is journaled at the top, as shown at 25. Threaded upon this screw within the tube 14 is a follower `26, adapted to eject the lubricant from the tube as the screw is rotated, whereby thefollower is caused to travel downwardly through the inner tube. This follower has a groove 4 formed in its periphery, which engages the tongue 2O of the inner tube, as the said follower is caused y to travel downwardly through the inner tube. To the upper extremity of the screw 24, outside of the cap 17, when the parts are assembled, is pivotally attached a U-shaped handle 27, which is adapted to facilitate the rotation' of 'the screw for the purpose of actuating the follower. This handle niember, when in position for actuating the screw, extends at right angles to the axis of the latter, while, when it is desired to remove the cap, the handle is brought int-o alinement with the screw, the top of the cap having an opening 28 large enough to receive said handle. This opening 28 is provided at one side with an extension 29 into which the inner extremity 30 of the handle protrudes when the latter is positioned to allow it to be brought into alinement with the screw. At all other times, the handle is prevented from assuming such position.

To the lower extremity of the outer tube 13 is secured, as shown at 31, a sort of neck 32, which is reduced, as shown at 33, to receive the upper extremity 34 of a pipe 35,'

which extends downwardly through an opening 36 formed in the hub 37 of the wheel, whose journal 38 is to be lubricated. This tube is open at both ends and the netal lining 39 of the hub is perforated, as shown at 40, to allow the lubricantto pass to the journal.

From the foregoing description, the use of my improved device will be readily understood. Assuming that it is mounted upon the vehicle wheel in the manner heretofore described, the device is charged with lubricant by first removing the cap 17 and then detaching the inner tube 14. This may be done by throwing the handle 27 into alinement with the screw 24 and then inserting a nail or other suitable device between the two parts of the handle and pulling straight outwardly. Resort to this expedient will usually be found necessary, because of the fact that the two tubes are so closely fittedV together at their inner extremities, in order to form a lubricant-tight joint, that there is considerable friction. After this tube 14 is removed, assuming that the fol-- lower 26 is located in the upper extremity of the tube, above a vent port 41, the tube 14 may then be charged with'lubricant by pressing the tube intoa quantity of relatively hard lubricant, with its lpen extremity foremost; The lubricant, by virtue of this manipulation, fills the tube from its lower extremity to the follower in the upper extremity, the air escaping during the filling operation through the vent port 41. The inner tube is then insertedvin the outer tube and' the ca replaced, after which the device is ready or use.

Having thus-.described my invention, what I claim isi:-

1. A lubricator including an outer tube and an inner tube, the inner tube being exteriorly grooved longitudinally, the outer tube having a projection at the top engaging suc'h groove to prevent the inner tube from turning' within the outer tube, the inner tube being equipped wit-h` a screw 'ournaled therein, a follower threaded on t e screw,

.the inner tube having an interiorly-projecting longitudinally-disposed tongue adapted to enter a recess formed in the follower to prevent the latter from turning during the rotation of the screw to actuate the follower, substantially as described.

2. A lubricator comprising an outer tube and an inner tube, the inner tube having an exterior groove and an interior tongue, thc outer tube having a pin projecting into the groove of. the inner tube, the.latter being equipped'with a follower recessed to engage the tongue of the inner tube, the outer tube being dented at the bottom to cause the material to enter the groove of the inner lube, the outer tube being inwardly flared at. the bottom to forni n light i;)int with the inner tube. for the purpose, set' lordi...Y
